ROBERT S. GOULD, OF EAST ORANGE, NE? JERSEY.

CARPET-FASTENER.

SPECIFICATION forming part of Letters Patent No. 323,575, dated August4, 1885.

Application filed May 22, 1885. (Modem T 0 (all whom it TIMI/Z] concern:

Be it known that I, ROBERT S. GOULD, of East Orange, county of Essex,and State of New Jersey, have invented certain new and usefulImprovements in GarpetFastencrs, of which the following is aspecification.

This invention relates to carpet-fasteners for attaching stair and othercarpets and rugs; and the invention consists of a fastener composed of acircumferentially-flanged and 6Xt6 riorly-threaded bottom plate, whichis attached by a nail or staple passing through a hole or holes of thesame, and of a cap rhatis screwed on. said bottom plate, and providedwith a raised center portion having nicks for applying a screw-driver.

In the accompanying drawingsFigure 1 rep resents an elevation of a fewsteps of a staircase, showing a carpet attached by my improvedfasteners. Fig. 2 is a front view of the carpet-fastener; Fig. 8, afront view and section of the bottom plate detached from the cap; andFig. 4 is a vertical transverse section of the fastener.

Similar letters of reference indicate corre sponding parts.

Referring to the drawings, bottom plate, and B the cap, of my improvedcarpetiastener. The bottom plate, A, is made of sheet or other metal,and provided with a circumferential flange, a, having an exteriorscrew-thread for screwing on the cap 13. The bottom plate, A, isprovided with one or two holes for passing through a nail or staple, b,by which. the bottom plate, A, is attached to the floor or riser of thesteps, as the case may be, so as to hold the carpet in position. \Vhenthe bottom plate is attached, the cap is screwed on so as to cover thenail or staple b. The screw-cap B is provided with a raised A representsthe center portion, (2, having nicks across each other at right anglesfor applying ascrewdriver thereto. By means of the nicks the cap can betightly screwed on the bottom plate and readily unscrewed therefromwhenever it is necessaryto take up the stair-carpet. By screwing the captightly on the bottom plate it is prevented from playing-loose andgetting lost.

The nicks on the raised center portion, (1, of the screw-cap B serve forunscrewing the cap when it is desired to take up the carpet, after whichthe nail or staple and the bottom plate are removed, so as to preventthe prying oli of the carpet-firstencr by inserting a tool below thebottom plate, which is objectionable, as it injures the bottom plate andrenders it unfit for use.

The carpet fastener the bottom plate can has the advantage that bereadily attached by driving in a nail or staple, after which the cap isplaced in position. It can be fastened quickly to the stairs or floor,and can be re moved without injury to the carpet or fastener. Thecarpet-fastener,by unscrewing the cap or head with a screw-lriver andlifting out the nail or staple by inserting the tool below the head ofthe same, resting the tool on the bottom plate, whereby the same is notinjured, forms a cheap and neat device for fast ening stair and othercarpets, and can be readily removed and replaced, as required.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent- A carpet-fastener consisting of a bottom platehavingacircumferential and exteriorly' threaded flange, a nail 0r staplepassing through a hole or holes of the bottom plate, and a detachablescrew-cap having a raised and nicked center portion, substantially asset forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
